摘要 在熔盐电解制备钛的TiO2阴极中掺杂不同比例的CaCO3粉末,采用SEM,EDS及XRD分析烧结后和电解后阴极的形貌及成分,考察了CaCO3的掺杂对电解提取钛反应过程的影响。结果表明:在TiO2阴极中掺杂CaCO3粉末可以增加烧结后阴极片的孔隙,影响TiO2颗粒尺寸的大小,有利于加快阴极电解反应的速度,提高电解效率。 TiO2 cathode CaCO3 was used for preparing Ti in melt electrolysis. The morphology and composition of TiO2 cathode, the impact of CaCO3 doping on TiO2 cathode were investigated. The results showed that CaCO3 doping in TiO2 cathode would increase the porosity of the sintered solid TiO2, affect the particle size of TiO2. The velocity and efficiency of electrochemical reduction of solid TiO2 to metallic Ti were increased.
